Question

Arrange the following Indian Satellites according to chronological order of launch:
• [(i)] INSAT
• [(ii)] Aryabhata
• [(iii)] EDUSAT
• [(iv)] GSAT

• A. (ii), (i), (iv), (iii)
• B. (ii), (iii), (i), (iv)
• C. (ii), (i), (iii), (iv)
• D. (ii), (iii), (iv), (i)

Hint:

Aryabhata (1975) $\downarrow$ INSAT (1982) $\downarrow$ EDUSAT (2004) $\downarrow$ GSAT Series

Answer 1

The Correct Option is C

Step 1: Identify the launch year of Aryabhata.
Aryabhata was India's first satellite. \[ {1975} \]

Step 2: Identify the launch year of INSAT.
INSAT-1A was launched in: \[ {1982} \]

Step 3: Identify the launch year of EDUSAT.
EDUSAT (GSAT-3) was launched in: \[ {2004} \]

Step 4: Identify the GSAT series launch.
GSAT satellites were launched after the INSAT series and continue as communication satellites. Thus the sequence accepted in the examination is: \[ {\text{Aryabhata} \rightarrow \text{INSAT} \rightarrow \text{EDUSAT} \rightarrow \text{GSAT}} \] \[ (ii) \rightarrow (i) \rightarrow (iii) \rightarrow (iv) \] \[ {\text{Option (C)}} \]
